### How does JobsPipe know a company uses JSON?

From the company's own job postings. Each posting is read for the technologies it names, and every company and technology pair is graded: confirmed when two independent checks agree on JSON in at least one posting, likely when it is a stated requirement or appears in two separate postings. A single passing mention is not counted here. It is evidence of a team working with JSON, not a purchase record.
